After about a quarter of an hour, after feeling the heat on his body subside, Lu Tianhui came back with the cow again.

He looked at the wolfskin unfolded to the side and asked, "What is this for?" ”

This man seems to be a book of 100,000 whys, Su Qingyan slapped his forehead, turned the roast wolf meat in his hand, and spit out three words impatiently.

"Make tires."

Tyre?

Another new word, Lu Tianhui still wanted to ask shamelessly, and a piece of fragrant barbecue was handed to him.

"Eat quickly, I'm not busy hunting today, and you can go to the creek to wash later, and I'll take care of your wounds." Su Qingyan said the arrangements for the meeting later, and took a bite of the crispy barbecue.

After eating, the two casually threw the bones into the trap dug straight forward, Su Qingyan loosened his muscles and bones, and walked deep into the forest.

She had several injuries on her arms and legs, and Lu Tianhui was similar, but she had to find some good medicine to disinfect it.

Seeing her leave, Lu Tianhui slowly stepped into the stream and washed his body.

His new coarse cloth clothes were stained with wolf blood, and the whole stream was red after soaking in the water, but the color on his body had receded considerably.

It's good to say that the water washed the wound, and the smell of blood on his body, so Lu Tianhui went ashore.

After a while, Su Qingyan found herbs.

"This plant is in the shape of a sharp leaf, bite it and put it on the wound for a quarter of an hour before washing it off," she handed two herbs to Lu Tianhui, and then pointed to the one thrown on the ground, "This will be ground into powder and bandaged later." ”

With that, she did it herself.

Although Lu Tianhui was nervous, he thought of what she said last time "salivary enzyme" seemed to have some effect on the wound.

Thinking about it, he did it.

Half an hour later, the two men who had bandaged their wounds transported the wolf's carcass to the bear den, and by the way, tied the big black bull into it.

After coming out of the bear hole, the two went back to the creek.

Because of the water source, the branches and leaves of the trees in this forest grow more lush than elsewhere, and Su Qingyan must choose the best wood if he wants to make an ox cart with strong load-bearing capacity.

Thinking about the old injuries on Lu Tianhui's body, Su Qingyan didn't let him contribute, and cut down a four-foot-thick tree by himself.

After chopping, she didn't stop, but said to Lu Tianhui, who was flipping the wolf skin on the side.

"Lu San, you first deal with these branches and leaves, and I'll draw the design of the oxcart."

After speaking, Su Qingyan picked up the branch and walked aside, rubbed a flat ground with the sole of his shoe, and then pinched the branch to write and draw.

When Lu Tianhui heard this, he put the wolf skin that had been a little sunburned on the stone, and then got up to deal with the trunk.

During this period, he also looked at Su Qingyan from time to time.

Looking at her appearance, she looks serious and decent, but I don't know what weird ideas there are

Su Qingyan sometimes rubbed his chin in contemplation, sometimes jumped up and down irritablely, but every time there was movement, he would add a few strokes to the ground.

About half an hour later, the branches of the tree had been cut down.

At this time, Su Qingyan also threw the branch to the ground in a dashing manner and patted the mud on his hand.

"Alright, you're done!"

Lu Tianhui took a closer look, and the appearance of the cart painted on the ground was very different from that of ordinary ox carts, even the palanquin in the palace was not so exquisite.

However, he was not stupid, and soon saw some doorways, "Is the low seat in front for people to sit on?" ”

Su Qingyan nodded.

This is her combination of modern cars painted, although this ancient engine can not be made, but the shape or something can still take its modern essence.

She pointed to the blueprint on the ground and said, "In front, the driver's seat and the co-pilot ......."

Seeing that this man was a little difficult to understand the new term, Su Qingyan's eyes rolled and he changed his expression.

"In other words, you have to be responsible for driving the cattle in the front."

Lu Tianhui nodded thoughtfully, looking at the four round wheels under the body, his face became even more condensed.

"An ox cart should be set up with two wheels and one axle, and these four wheels not only do not play a role, but may also repel each other."

What kind of rebuke of the four wheels? Su Qingyan rolled her eyes angrily.

She didn't bother to explain so much to this man.

"Okay, okay, you just listen to me, hurry up and take a taxi, and if you grind it any longer, the sun will go down." Su Qingyan said as he took the saw and began to saw wood to make wheels.

The ancients only drove on two wheels because they could not control the direction of the front wheels, and they completely relied on the brute force of livestock to pull, and had to overcome a lot of friction between the wooden wheels and the ground.

She now uses hard and elastic wolf skin attached to the outside of the wooden wheel to make the wheel, which can save at least half the effort to pull the car, and the bottom of the car with a few axles is almost the same as a bicycle.

Lu Tianhui didn't understand her thoughts, so he just helped with some small work on the side.

In half a day, Su Qingyan made four identical wooden wheels.

Just when the sun was about to set, the wolf skin that had been dried for a day had almost dried up, and the toughness was just enough to make a tire.

"It's a pity that you can't pump up, if you make an air tire, the speed will definitely be good." Su Qingyan touched the skin and muttered.

"What?" Vaguely hearing her muttering, Lu Tianhui asked in a low voice.

"It's nothing, it's getting dark, let's go down the mountain quickly." Su Qingyan said.

The two of them carried the ox-cart tree and the wolf's skin down the mountain.

The people in the village often saw Su Qingyan and Lu Tianhui coming down from the back mountain with a lot of things, and they were already surprised.

But after returning to the Su family, the Su Wang family did not follow.

"What about the cow you bought yesterday?" She has a calm face, and she looks like she relies on the old and sells the old.

Su Qingyan didn't say anything politely, she glanced at Su He, who was silent, with a smile, and then said word by word.

"Last night, my aunt and uncle came to the door of my house in the middle of the night to see the cow, I was not at ease, so I hid the cow, what's the matter, you also have this idea?"

As soon as these words came out, Su He's face turned red.

But she's not a good-tempered lord, she was startled last night and didn't sleep well all night, she was already angry, and now she is getting more and more angry.

She gritted her teeth......

"Cheap skin, don't spew blood, keep saying that your uncle and I want to steal cattle, so come up with evidence!

”

Su Qingyan pouted indifferently, "I don't have the evidence, but if you have the idea of fighting the bull again, I'm not welcome." ”

Rao was an understatement, but it still made Su Wang and the others shudder.

I thought they would have to entangle for a while before they stopped, but it happened that Aunt Su in the main house shouted for dinner, and they all dispersed

Thinking that he would have to make an ox cart later, Su Qingyan quickly cooked.

Inside the main house.

Su Wang's family didn't see the cow, and the depression in his heart became stronger and stronger, and he knocked on the chopsticks and patted the bowl when he ate.

Seeing the old woman like this, everyone didn't dare to make a sound.

"Dafang's family, did you really go to steal cattle last night?" Su Wang put down the dishes and chopsticks and said suddenly.

Hearing this, Su Dazhuang "chuckled" in his heart, could it be that everyone knew about this? He was born honest, not good at lying, and wanted to admit it.
